An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

y ∝ x

y = kx

Where k is a constant and it can be any integer.

If y varies directly with x.

Yes, it is possible to determine by how much y increases or decreases as x increases.

If x increases by 2 then y also increases by 2.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

y varies directly with x.

This can be written as an equation,

y ∝ x

y = kx

Where k is a constant and it can be any integer.

Now,

If x increases by 2.

y = 2k

If k = positive integer

Then y will increase by 2k.

If k = negative integer

Then y will decrease by -2k

So,

Yes, it is possible to determine by how much y increases or decreases.

Thus,

If y varies directly with x.

Yes, it is possible to determine by how much y increases or decreases as x increases.

Actually Welcome to the Concept of the Probabilities.

Here, In the game of cards, we have total number of 52 cards in a deck. Since here we have to find the probability of Card 6 from the whole deck.

Let's solve,

Total Number of Cards we have = 52

Total number of 6 numbered Cards in deck = 4

Hence, probability = Favourable Outcomes ÷ Total No. of Outcomes.

So, the Probability of getting a 6 Card = 4/52

= 1/13

Hence the probability is 1/13.

Answer:

the answer is E

Step-by-step explanation:

We want to find how many integers are between 2020 and 2400 such that a criteria is meet, and the criteria is that the four digits are different and are arranged in increasing order.

We will see that there are 15 of these numbers between 2020 and 2400, so the correct option is C.

---------------------------

To count the number of digits that meet the given criteria, we first need to analyze how the criteria is.

If the numbers must be in increasing order, then the smallest number that can be in the hundreds place is 3 (the smaller integer larger than 2).

so we have:

23__

The number next to the 3 can be a 4, for example:

234_

And the final number can be any number larger than 4, so we have {5, 6, 7, 8, 9} a total of 5 options.

If instead of a 4, the number next to the 3 is a 5, we have:

235_

And the number next to the five can be any digit larger than 5, so now we have 4 options.

Now, we can't have another number than a 3 in the hundreds place, because if we put a 4 there, we are out of the range, and 3 is the smallest digit that we can use there.

Then we already saw all the possible numbers that we can make, adding the numbers of options that we got above we will get:

5 + 4 + 3 + 2 + 1 = 15

This means that are 15 of these numbers between 2020 and 2400. Then the correct option is C.

Answer:

y = 5x + 9

Step-by-step explanation:

Assuming you require the equation of the line.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 5, thus

y = 5x + c ← is the partial equation

To find c substitute (- 1, 4) into the partial equation

4 = - 5 + c ⇒ c = 4 + 5 = 9

y = 5x + 9 ← equation of line

t = 3.4285 or 24/7

Step-by-step explanation:

Sub f = 2t + 1 into the other equation

7(2t + 1) = 55

14t + 7 = 55

Rearrange

14t = 55 - 7

14t = 48

t = 3.4285 or 24/7

Answer:

$150.66

Step-by-step explanation:

Let that amount of money Roger has = x

The amount of money Roderick has = y

Roger has four dollars more than double the amount that Roderick has in his wallet.

x = 2y + 4

Together, they have a total of $224.

x + y = $224....... Equation 1

We substitute 2y + 4 for x in Equation 1

2y + 4 + y = $224

3y + 4= $224

3y = $224 - 4

3y = $220

y = $220/3

y = $73.333333333

y = $73.33

How much money does Roger have?

x = 2y + 4

x = 2(73.33) + 4

x = $146.66 + 4

x = $150.66

Roger has $150.66

Answer:

y=-5/2x-4

Step-by-step explanation:

y-l=-5/2(x+2)

y=-5/2x-4

Answer:

Assuming its "Modeling a Water Wheel" from EDGE its

Distance: a= 1/2 b=1 c=3/2

Heights: d=1  e=0  f=-1

Step-by-step explanation:

The solution is, a = 6, b = 7, c = 8, d = 7 and e = 6.

Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.

here, we have,

Let's remember that the complete revolution of the wheel is 360 degrees, and the distance traveled by a complete revolution is the length of the circumference: 2*pi*radius.

The inicial height of the point is 6 ft, and the radius of the wheel is 1 ft.

When the distance traveled is 0, the wheel turned 0 degrees, and the point will be in its inicial position (the lower position of the wheel), which is 6 feet high.

So the height will be a = 6 + 0 = 6 ft

When the distance traveled is pi/2, the wheel turned 90 degrees, and the point will be half the complete height of the wheel, which is 2 feet.

So the height will be b = 6 + 1 = 7 ft

When the distance traveled is pi, the wheel turned 180 degrees, and the point will be at the top of the wheel, which is 2 feet higher than the lower point of the wheel.

So the height will be c = 6 + 2= 8 ft

When the distance traveled is 3pi/2, the wheel turned 270 degrees, and the point will be half the complete height of the wheel, which is 2 feet.

So the height will be d = 6 + 1 = 7 ft

When the distance traveled is 2pi, the wheel turned 360 degrees, and the point will be in its inicial position (the lower position of the wheel), which is 6 feet high.

So the height will be e = 6 + 0 = 6 ft

So the answers are:

a = 6, b = 7, c = 8, d = 7 and e = 6

#SPJ7

Answer: it is 564 miles to her destination

Step-by-step explanation:

The slope of a linear line (or a linear equation) can be found by simply taking 2 values for x and y and then using the slope formula which is [tex]\frac{dy}{dx}[/tex] or:

[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

Example:

Let's say you're give this table:

x: 1, 2

y: 1, 2

Following the steps which I gave, you take 1 value for the y (preferably the larger one) which in this cause will be 2 and then another y from the table which would be 1

Do the same for x

Now plug the values taken in the slope formula and you get:

[tex]\frac{2 - 1}{2 - 1}[/tex]

[tex]\frac{1}{1} = 1[/tex]

Therefore the slope is 1.

Answer:

Rise/run

Rise over run.

Step-by-step explanation:

To find the slope pick two perfect spots on the line when the coordinates are not decimals.

Then, take those  two points and figure out the distance. You will use rise/run.

so rise is how much you either go up or down and run is how much you either go right or left. so how much you'll go up or down? how much will you move right or left?

Lets say you have to go up 5 and then left 7 to get to the coordinate.

That's your slope! you went up so it's positive and you went left so it's negative. Rise over run : rise 5 left 7 so, 5 and -7 which is 5/-7 and that's your slope!

opportunity cost

The actions that cannot be taken as a result of an action that is taken are known as the opportunity cost of the actions taken.

" he opportunity cost of a particular activity option is the loss of value or benefit that would be incurred by engaging in that activity, relative to engaging in an alternative activity offering a higher return in value or benefit."

Let say, a homeless man has only $8. He is hungry and don't have cloths to wear. Now, if he buys a burger and some chocolates with all the money he has, then he cannot use that money to buy anything else.  

Therefore, he will not be able to buy any cloth as he spent his money on food. If there is any t-shirt available at the same cost, then the cloth is the opportunity cost.

Therefore, the actions that cannot be taken as a result of an action that is taken are known as the opportunity cost of the actions taken.
